When any of the following DTC's has been detected, the ECU enters the fail-safe mode in order to make it possible for the vehicle to drive for evacuation and to ensure safety. When the malfunction is remedied to a normal condition, the fail-safe control will be released.

However, the diagnosis results will remain memorized. Hence, it is necessary to determine whether the mal-function still persists or not.

31

When the signal from the intake manifold pressure sensor exhibits an open wire or short circuit

• The signal from the intake manifold pressure sensor is set to the value determined from the throttle opening angle, engine revolution speed and ISC opening angle.• The ignition timing is changed to the control based on the pressure determined from the engine revolution speed and the above value• The fuel will be *out* when the throttle opening angle and engine revolution speed exceeds the respective set values.

43

When the signal from the intake air temperature sensor exhibits an open wire or short circuit

• The signal from the water temperature sensor is set to a constant value.

42

When the signal from the engine coolant temperature sensor becomes open or shorted.

• The signal from the engine coolant temperature sensor becomes a constant value * At this time, the radiator fan is turned on, (Except for EU spec. )

41

When the signal from the throttle position sensor exhibits an open wire or short circuit

• The signal from the throttle position sensor is set to a constant value

22*1

When an abnormality is encountered in the signal from the rear 02 sensor

• The feedback of the rear O2 sensor is slopped• The correction coefficient of the feedback of the rear O2 sensor is set to the value determined from the engine revolution speed and pressure

18*3

When the signal from the knock sensor becomes open or shorted

• The ignition timing is retarded.

32*1

When the signal from the atmospheric pressure sensor exhibits an open wire or short circuit

• The signal from the atmospheric pressure sensor is set to a constant value

36*1

When the Ion current signal аrom me ignitor unit becomes open or shorted

• The ignition timing is retarded.

73

When an abnormality is encountered in the valve timing control

• The learning of the most retard timing is prohibited • The control of air-to-fuel ratio learning is prohibited • The idle speed control is changed

44

When the signal from the evaporator temperature sensor exhibits an open wire or short circuit for more than a certain length of time

• The air conditioner will be cut

83*2

When abnormality occurs in writing and reading-out of the rolling codes into/from the E2 PROM during the immobilizer communication

• The injection and ignition are prohibited. (Only for vehicles with the EU. Israel. AUS and Saudi Arabian specifications)

81*2

When the rolling codes cannot be exchanged between the EFI ECU and the immobilizer ECU or the rolling codes are not matched

• The injection and ignition are prohibited. (Only for vehicles with the EU. Israel. AUS and Saudi Arabian specifications)
